  Conformationally constrained analogues of diacylglycerol (DAG). Part 19: Asymmetric syntheses of (3R)- and (3S)-3-hydroxy-4,4-disubstituted heptono-1,4-lactones as protein kinase C (PK-C) ligands with increased hydrophilicity

  摘要：

  The stereospecific introduction of (R)- and (S)-OH groups at position C-3 of two diacylglycerol gamma-lactones (DAG-lactones) previously identified as strong protein kinase C (PK-C) ligands is presented. The compounds were designed to investigate whether the extra OH group in a specific orientation could establish an additional hydrogen bond with the C1 domain of PK-C, thus providing a DAG analogue with reduced lipophilicity. The OH groups were introduced following two different diastereoselective multistep syntheses starting from diacetone-D-glucose. The PK-C binding affinities for the new compounds were weaker in comparison to those of the parent compounds, suggesting that the extra OH does not engage efficiently in hydrogen bonding at the receptor.

  A new class of conformationally constrained nucleosides, α-l-ribo-carbocyclic LNA thymidine (α-l-carba-LNA-T, LNA is an abbreviation of locked nucleic acid) analogues and a novel “double-locked” α-l-ribo-configured tetracyclic thymidine (6,7′-methylene-bridged-α-l-carba-LNA-T) in which both the sugar puckering and glycosidic torsion are simultaneously constrained, have been synthesized through a key

  一类新的构象受限的核苷，α-的升-核糖-碳环LNA胸苷（α-升-carba-LNA-T，LNA是锁核酸的缩写）类似物和一种新颖的“双锁定”α-升-核糖结构的四环胸苷（6,7'-亚甲基-桥联的-α- 1-碳-LNA-T），其中糖的起皱和糖苷的扭曲同时受到限制，这是通过涉及5- exo游离的关键步骤合成的-自由基分子内环化。这些α- l-carba-LNA类似物随后已转化为相应的亚磷酰胺，并掺入了等序反义寡核苷酸（AONs）中，然后对它们的双链体进行了热变性，核酸酶稳定性和RNase H募集能力进行了研究。与天然异源双链体相比，在AON / RNA异源双链体的AON链中引入单个6'，7'-取代的α- 1 -carba-LNA-T修饰导致T m降低2-3°C，而已发现在AON链中相同位置的亲本2'-oxa-α- 1 -LNA-T修饰导致T m增加3-5°C。这表明6'和7'取代导致修饰的异源双链体的热稳定性大大降低，尤其是位于α
